Aliasing Phone Numbers to Email Addresses

Call Tracking Metrics provides an area to add notes about the caller. They provide a field for you to enter the caller’s email address, if you know it (click the screenshot to expand):

Entering an email address aliases the email to the caller’s phone number, so that events registered under either ID will represent the same person in Kissmetrics. This is key in tying together the call information you receive from this integration to the existing data you already collect online in Kissmetrics.
